Chlorido{5,10,15,20-tetra­kis­[2-(2,2-dimethyl­propanamido)­phen­yl]porphyrinato-κ4 N,N′,N′′,N′′′}iron(III) chloro­benzene hemisolvate monohydrate

In the title complex, [Fe(C64H64N8O4)Cl]·0.5C6H5Cl·H2O, the equatorial iron–pyrrole N atom distance (Fe—Np) is 2.065 (2) Å and the axial Fe—Cl distance is 2.207 (2) Å. The iron cation is displaced by 0.420 (4) Å from the 24-atom mean plane of the porphyrin core. The asymmetric unit contains a quarter of an [FeIII(C64H64N8O4)Cl] complex mol­ecule, with a fourfold rotation axis passing through the central metal cation and the Cl ligand, along with disordered mol­ecules of chloro­benzene and water of solvation; the solvent mol­ecules were excluded from the refinement

(Cryptand-222)potassium(+) (hydrogensulfido)[5,10,15,20-tetra­kis(2-pival­amido­phen­yl)porphyrinato]ferrate(II)

As part of a systematic investigation for a number of FeII porphyrin complexes used as biomimetic models for cytochrome P450, crystals of the title compound, [K(C18H36N2O6)][FeII(C64H64N8O4)(HS)], were prepared. The compound exhibits a non-planar conformation with major ruffling and saddling distortions. The average equatorial iron–pyrrole N atom [Fe—Np = 2.102 (2) Å] bond length and the distance between the FeII atom and the 24-atom core of the porphyrin ring (Fe—PC= 0.558 Å) are typical for high-spin iron(II) penta­coordinate porphyrinates. One of the tert-butyl groups in the structure is disordered over two sets with occupancies of 0.84 and 0.16
